Methylisothiazolinone (MI): problem preservative

I've written a lot about a preservative called methylisothiazolinone (MI) recently. Here is some key information about it, but you can jump down to the section on recommended products for those diagnosed with MI allergy, if that's what you're looking for, or see the 'Cosmetics' or 'Household' sections of the Methylisothiazolinone Free site for listings of suitable household goods by category, as well as cosmetic brands which don't use MI.

The MI Story 
In 2013, two dermatological organisations issued warnings about a relatively new 'epidemic' of allergy to MI - a preservative present in wet wipes, skin creams, washing up liquid, sun care, fabric conditioners and many more household cleaners and personal toiletries.

Despite calls for a ban from some quarters, it seems industry has been moving towards only a partial ban (on 'leave on' products - i.e. skin creams) and continuing to permit use in 'rinse off' products at a low level (0.01% or less) which experts believe should not cause sensitisation to MI. This should, in theory, halt the epidemic. However, those already sensitised will have to continue to read labels on products such as kitchen cleaners, shampoo and shower gels to avoid it.

It seems those with eczema are more susceptible to sensitivity to MI (and other isothiazolinones, such as methylchloroisothiazolinone - or MCI), and as those with eczema are more likely to be atopic, they're also more likely to have food allergies. It's possible that those who experience reactions to skincare products and put them down to the food ingredients often found there, may actually be reacting to non-food ingredients - such as fragrances (such as linalool, geraniol, eugenol etc) and preservatives such as MI.

If you think you might be one of them, do not self diagnose. See a doctor or dermatologist who can, if relevant, refer you for patch testing to identify the culprit - although that may not be easy. You may find this article on Contact Dermatitis useful.

Avoiding fragrances and SLS (sodium lauryl sulphate) may also help if you have skin sensitivities. Here are some MI-free products.
